摘要
2000年在象山港3个养殖区(海带、牡蛎、鱼类)和非养殖区水域进行了四季调查,对养殖区和非养殖区大型底栖生物的生态学进行比较研究。调查鉴定出71种大型底栖生物,其中养殖区45种、非养殖区61种,两区共有种为35种。牡蛎养殖区外侧、鱼类网箱养殖区周围平均生物量和密度分别高达433.53g·m-2和155ind·m-2、91.92g·m-2和114.96ind·m-2;海带养殖区仅为1.55g·m-2和27.5ind·m-2,也明显低于非养殖区5.24g·m-2和53.04ind·m-2;鱼类网箱养殖区中心未见生物分布。本文同时对底栖生物与养殖生物、沉积物及水文环境因子的相关性作了研究探讨。
Seasonal investigations were carried out for 3 cultured areas (of algae, oyster and fish) and noncultured area in Xiangshan Bay. 71 species from study areas were identified. 45 species of them were collected in cultured areas, 61 species in noncultured area, 35 species from both cultured and noncultured areas. The biomass and density in oyster and fish cultured areas were 433.53g·m-2 and 155ind·m-2, 91.92g·m-2 and 115ind·m-2 respectively. It was higher than that in algae cultured area and noncultured areas. The biomass and density in algae cultured area were 1.55g·m-2 and 27.5ind·m-2,which was lower than that in noncultured area (5.24g·m-2 and 53.04 ind·m-2). No macrobenthic species was found in the center of fish cultured area. The relativity of the benthos with sediment, reared biology and hydrographic factors is discussed.
